scsi: ufs: core: Add debug log for UIC command timeout
It is difficult to debug when a UIC command timeout occurs simultaneously
with a UIC command complete interrupt. Currently, we only see the timeout
log without any debug information, making it unclear whether the UFS device
failed to respond or the host entered an incorrect state. Add a one-line
log to cover this situation.
